Episodic acidification from acidic precipitation in Coastal Plain streams of the Chesapeake Bay watershed is a potential threat to spawning and survival of anadromous fish species. The study is part of a process of selection of streams for mitigation of acidic episodes to increase the spawning success of anadromous fish stocks. It describes the development of practical, empirical models to predict the chemical response of Coastal Plain streams during precipitation events. One of the design criteria for the models was that they predict the response of a stream to precipitation events using data that are relatively easy to obtain. Data used to build and test the models were from several intensive studies of episodic acidification in the Maryland Coastal Plain. Regression models were developed to predict minimum pH during an event, change in pH during an event and minimum ANC (alkalinity) during an event. Two models were developed for each dependent variable.
